604-2Z Bearing Product Overview & Core Advantages
The 604-2Z is a metric single row deep groove ball bearing designed for high precision and reliability in compact spaces. Its key advantage lies in its ability to efficiently handle radial loads while its shielded (2Z) construction protects against contamination. Manufactured to a P6 tolerance class and pre-lubricated with grease, this bearing offers consistent performance, making it an ideal choice for applications demanding smooth operation and long service life without maintenance.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 604 | Basic bearing series, indicating a metric, single row deep groove design with a 4mm bore. |
| 2Z | Specifies shielded construction on both sides. The shields protect the internal components from dust and other contaminants while retaining the lubricant, contributing to the bearing's maintenance-free characteristics. |
604-2Z Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Built to P6 tolerance class with tight dimensional control on the bore, outside diameter, and width, ensuring precise fit and stable operation. The single row deep groove raceway provides robust support for radial loads.
- Optimized for Compact Designs: With dimensions of just 4mm (bore) x 12mm (OD) x 4mm (width) and a low weight of 0.0021 kg, this bearing is engineered for applications where space and weight are critical constraints.
- Durable Material Construction: The use of Chrome Steel for rings and balls, combined with a Stainless Steel cage, ensures high strength, wear resistance, and corrosion resistance for extended bearing life.
- Ready-to-Use & Maintenance-Free: The bearing is pre-lubricated with grease and features non-contact shields (2Z), making it a sealed-for-life unit. This eliminates the need for relubrication and protects against contaminant ingress.
- Reliable Performance: A radial dynamic load rating of 181 lbf and a limiting speed of 60,000 rpm demonstrate its capability to perform in demanding, high-speed scenarios.
604-2Z Bearing Typical Application Areas
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Office Automation Equipment: Used in printers, scanners, and copiers for paper feed rollers and scanner heads.
- Medical Devices: Suitable for small pumps, dental handpieces, and diagnostic equipment requiring quiet and precise rotation.
- Instrumentation and Control Systems: Applied in encoders, gyroscopes, and other sensitive measuring devices.
- Consumer Electronics: Found in computer cooling fans, drones, and small power tools.
